If that is all you did, then you have not installed the smeserver-hwinfo contrib, which explains why nothing is visible in the Configuration section of the server-manager.
That's what I figured Charly,
I initially looked up wiki.contribs.org/SME8.0_Contribs_QA which said "install as per wiki, works as expected "
but the wiki.contribs.org/Hardware_Info says to
"yum install --enablerepo=smecontribs smeserver-hwinfo" which results in
"No package smeserver-hwinfo available."
So then I tried
"yum --enablerepo=smecontribs list" which has no hwinfo in the list, only lshw: so I installed that,
recognising the result of a command line only outcome,
but I am at a lose to know what else to do.
any advice on where my thinking went astray would be appreciated
